Apparently there is a time-lag between the day on which a msn suffers a coronary and the day on which he develops a stroke.
This conclusion was reached by local scientists recently aft­er they had studied hundreds of brain arteries which they had carefully divided into age groups.
JDr. John Moossy, professor of neurology and pathology at Louisiana State University Med­ical School, said if their con­clusion is correct, the next step will be to devise a treatment which can be used during the time-lag to help prevent the ex­pected stroke.
For the past two years, Dr. Moossy has headed a research project which calls for the anal­ysis and study of literally thou­sands of human brain arteries». collected from all sections of the world.
FROM OSLO TO CHILE Today brain arteries are be­ing collected in Oslo, Norway, in Turin, Italy, in Guatemala City, on the island of Jamaica, in Santiago, Chile, and in New Orleans.
After the arteries are as­sembled they are carefully pro­cessed. Then they are dis­patched to the main clearing house at Louisiana State Uni­versity in New Orleans.
Dr. Moossy said at autopsy the complete blood supply to the brain is removed.
"This means removal of all arteries leading to the brain, including the carotid and vete-bral arteries which, as you know, are the two main blood vessels in the neck," the sci­entist explained. "These arter­ies are the ones which the surgeons clean out in an at­tempt to cure strokes in a group of specially - selected cases."
The neurologist said he and his co-workers are also study­ing the blood vessels inside the brain — "those blood vessels which surgeons are presently unable to repair."
"Up unnrnow we nave re­ceived 1,400 arteries from all over the world," he explained. "Since we have completed a detailed analysis of only about a quarter of these arteries, ov­er-all conclusions are not possi­ble at this time."
